How the Unit Determines When to Alarm
Your Carrier CO alarm uses advanced technology to monitor
the environment in your home and warn you of unacceptable lev-
els of carbon monoxide. An internal microcomputer works
together with the sensor inside the alarm to determine the lev-
els of carbon monoxide in the air and to calculate the rate that
CO would be absorbed into the human body. The microcom-
puter is calibrated to trigger the unit’s alarm before most people
would experience any symptoms of carbon monoxide poison-
ing. Because carbon monoxide is a cumulative poison, long-
term exposures to low levels can cause symptoms, as well as
short-term exposures to high levels. Your unit has a time
weighted alarm, so the higher the level of carbon monoxide
present, the sooner the alarm will be triggered.
WARNING: This device is designed to protect individuals from
acute effects of carbon monoxide exposure. It will not fully
safeguard individuals with specific medical conditions. If in
doubt, consult a medical practitioner. Individuals with medical
problems may consider using warning devices which provide
audible and visual signals for carbon monoxide concentrations
under 30 ppm.
Replacement of Alarm
Eight years after initial power-up, this unit will “chirp” every 30
seconds to indicate that it is time to replace the alarm. A label
has been provided that has “Replace by” printed on it. Write
the replace by date on the label and affix it to the front of the
alarm so that it is visible after mounting. The date written on
the label should be after eight (8) years of cumulative power
.
REPLACE IMMEDIATELY! UNIT WILL NOT DETECT CO IN THIS CONDITION.
